Generalised Kinematic Single‐Impact and Multi‐Impact Models for Rocking Structures

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The rocking motion is fundamental in earthquake engineering, as it reflects the dynamic behaviour of many structural systems. However, simulating the impacts during rocking motion remains a challenging topic, as they occur in a very short time, generate high impulsive forces, cause sudden changes in velocities and result in rapid energy losses.

Noise, Vibration, and Harshness (NVH) Challenges in Hydrogen Internal Combustion Engine Vehicles

Energy Science &Engineering, EarlyView.
ABSTRACT This paper presents a state‐of‐the‐art literature review on noise, vibration, and harshness (NVH) in hydrogen‐fuelled internal combustion engines. Studies published between 2011 and 2025 were screened, covering fundamental flame physics, test‐bench work, and recent prototype vehicles.

Critical Review on the Molecular Behavior of Surfactants at the Oil–Water Interface During Oil Displacement

Energy Science &Engineering, EarlyView.
This review systematically explores the molecular behavior of diverse surfactants (anionic, cationic, nonionic, amphoteric) at the oil–water interface through molecular dynamics simulations. It highlights their roles in reducing interfacial tension, altering interfacial structure, and enhancing oil recovery efficiency.

Research on Thermal Runaway Multiphysics Coupling Simulation and Sensor Optimization Layout of Lithium Iron Phosphate Energy Storage Battery Packs

Energy Science &Engineering, EarlyView.
This study explores thermal runaway in lithium‐iron‐phosphate energy storage battery packs through multi‐physics coupling simulation. Thermal runaway evolves from battery cells (experiencing overcharge, bulging, safety valve opening, and gas venting) to battery clusters (a) and propagates within the battery pack (b). Simulation results indicate: stress

Analysis of Turbulent Modeling for Free‐Surface Flows Using a Hybrid RANS‐LES Model and Particle‐Based Moving Particle Semi‐Implicit Method

International Journal for Numerical Methods in Fluids, EarlyView.
A hybrid RANS‐LES turbulence model adapted for the Moving Particle Semi‐implicit method is employed to investigate a turbulent free surface flow. A method based on the cell‐linked list is proposed to speed up the nearest wall search for the turbulence model.
